How big would the blast radius of Yellowstone be?

How big would the blast radius of Yellowstone be? Based on past research and the general location of the volcano itself, the blast radius of Yellowstone's calderas is quite large. When it comes to lava and magma flows spewing forth from this volcanic eruption, Yellowstone National Park would likely need to evacuate everyone within a 40 to 50 mile radius.

What would most likely be a super eruption of Yellowstone?

The most likely explosive event to occur at Yellowstone is actually a hydrothermal explosion (a rock hurling geyser eruption) or a lava flow.

What happens if Yellowstone blows up tomorrow?

If another large, caldera-forming eruption were to occur at Yellowstone, its effects would be worldwide. Such a giant eruption would have regional effects such as falling ash and short-term (years to decades) changes to global climate.

How far would Yellowstone volcano affect?

Yellowstone Super Volcano FAQ If the Yellowstone supervolcano ever erupted, it would bring about a calamity for most of the United States. The supervolcano would spew deadly volcanic ash for thousands of miles across the entire country.

What would happen if Yellowstone was nuked?

For an eruption to occur, a volcano needs a large amount of liquid magma and enough pressure to make it ascend to the surface. While nuking Yellowstone may not cause it to erupt, a nuclear blast on U.S. soil will inevitably be very damaging to both animal and human life.

What are the 3 super volcanoes in the US?

Would Florida be affected by Yellowstone?

Yellowstone volcano eruption simulations show an unexpected blast would produce ash fallout from the Northwest US down to the southern tip of Florida. Volcanic ash fallout of more than 39.4 inches (one metre) would blanket Yellowstone's immediate vicinity in the states of Wyoming, Montana and Utah.

Would Yellowstone cause an ice age?

No. A very large volcanic eruption would cause a severe cold period called a volcanic winter, but not an ice age. Volcanic eruptions cool the planet by creating a fine aerosol of sulfuric acid in the stratosphere. The highly reflective droplets prevent a portion of the sun's light from reaching and heating the surface.

How far would a Yellowstone eruption spread?

The total energy released would be equivalent to an 875,000 megaton explosion. The shockwave would kill 90,000 people. Most of the lava would fall back into the crater. Any flows would be slow and only spread 40-50km or so.

What is the biggest threat in Yellowstone?

Yellowstone's greatest geological threat isn't a supervolcano. It's a magnitude-7 earthquake. YELLOWSTONE NATIONAL PARK, Wyo. – While concerns about a potential eruption of the supervolcano beneath this iconic park may garner the most alarming headlines, a more likely hazard in the coming decades is a large earthquake.

What states would be destroyed if Yellowstone erupts?

Those parts of the surrounding states of Montana, Idaho, and Wyoming that are closest to Yellowstone would be affected by pyroclastic flows, while other places in the United States would be impacted by falling ash (the amount of ash would decrease with distance from the eruption site).

What volcano would destroy the world if it erupted?

Yellowstone Supervolcano (Wyoming, United States) Effects of a major eruption: When the Yellowstone Caldera, or supervolcano, in Yellowstone National Park erupts again, its effects would be worldwide, the U.S. Geographical Survey said.

Would New York be affected by Yellowstone erupting?

If the big volcano, which last erupted 640,000 years ago, were to blow up again, it would spew enough ash to send particles as far away as New York City.

Would the big one cause Yellowstone to erupt?

So strong earthquakes can indeed have an impact on volcanoes. But triggering eruptions? That's not common, especially in the mainland USA, where hundreds of M7+ events have clearly had no impact on volcanoes like Yellowstone, Long Valley, Coso, and elsewhere.

Where is the safest place to be if Yellowstone erupts?

A: For the most likely type of volcanic eruption in Yellowstone, everywhere would be safe except in the immediate vicinity of the advancing lava flow. In the highly improbable event of a large catastrophic eruption, the great the distance from the eruptive center, the safer it would be.
